Specification of l'teissued Letters Patent.

Reissued Nov. 8, 19.21.

Original No. 1,225,428, dated May 8, 1917, Serial No. 113,467, filed August 7, 1916. Application for reissue filed. May 31, 1919.

To all whom it may concern:

Be it known that I, JOSEPH W. GAMBLE, a citizen of the United States, residing at Boone, in the county of Boone and State of Iowa, have invented new and useful Improvements in Tractor-Binder Hitches, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to improvements in tractor binder hitches, and has for its object the production of a device, the use of which Wlll permit the turning of square corners and insure a uniform cut.

A further object is the production of a device by means of which the width of the swath out may be regulated.

A further object is the production of a device in which the outer end of the binder may be kept from swinging forward or back as desired.

A further object is the production of a device of cheap and simple construction, easily adjustable to fulfil various uses to which it may be put and not liable to disarran ement of parts. I

T liese and such other objects as may hereinafter appear are obtained by my device, an embodiment of which is illustrated in the accompanying drawings in which Figure 1 represents a perspective view of my device attached to the rear-of a tractor and front of a binding machine; and

Fig. 2 represents an enlarged top plan view of my device.-

Like numerals of reference indicate 'like parts in the several fi ures of the drawings.

' Referring now to t e drawing, in Fig. 1' is shown my improved binder hitch A "in operative osition' between the tractor B and a binder the device being rigidly secured to the tractor beam bar 13. The device proper comprises a cross bar 4 on either side of which are mounted retaining plates 5 secured between 'the plates. A draft bar is secured at itsrear end between the plates 5, and a. grain bar 8 is secured at its rear end between the plates 6.; The forward end of the draft bar .is pivotally secured to an extension bar 9 and the extension bar is rigidly secured to the,

t-tractorrbar 3 by means of bars 1010..

grain side opposite the end of the grain bar 8. A movement translator-bar 12 is pivotally mounted on the draft'bar at 13, a bar 14 being secured at the top and bottom of the plate and raised from the surface permitting the movement of the movement translating bar over the surface of the plate, the bar serving to retain the movement translating bar in operative position without any undue strain on the pivot.

The movement translating bar is connected at its grain end to the end of the grain bar 8, the end of the grain bar being rovided with a plurality of bolt holes 15, and the end of the movement translating bar having corresponding bolt holes 16 permitting a variety of adjustments. between the ends of the two members. The stubble side of the movement translating-bar is pivotally connected to a cross bar 17, the cross bar being provided with a plurality of boltholes 18 permitting a similar adjustment between the .two members. The upper end of the cross bar 17 is pivotally connected at 19 to the grain end of the extension bar 9, this bar also having a plurality of bolt holes 19 on the grain side, and additional bolt holes 2020 on the stubble side, as will be explained later. V

The plate 11 is provided with a plurality of bolt holes 21 positioned in the arc of the circle, the center of which is the pivotal point 13, and a bolt. hole .22 is positioned 1n the movement translating bar'and ada ted to register with the bolt holes 21mak1ng it possible, by the insertion of, a bolt through 21, to rigidly secure and lockthe movement translating bar in any desired position and rigid with the draft bar. The connection between the device and the binder maybe effected by pairs of clevises 23%24 swingingl secured to the rear bar 25 of the binder. X tiltin bar 26 is also provided pivotally mounted on the draft bar .as-at 27 and on the binder at 28. It will be noted that by. reason of the various bolt holes provided in the various members andplates a uniform variety of adjustments of the various parts ofthe device may be effected.

Referring-now to the operation of my device in the form illustrated I show the ,de-

}vice in its normal position with the crossbar v attached to-the grain end of the extension.

to adjust the cut of the binder by moving the lever at the front end of the grain bar forward or back. The binder hitch mechanism shown and above described may be readily converted into a rigid draft member that will prevent any relative swinging movement between the binder and the draft vehicle by removing the bolt 19, which locks the forward end of the cross strap from the attachment bar 9, and swinging the bar to a position so that the cross bar may be united with the opposite end of said attachment bar by means of a pin as 20. This makes a rigid hitch.

1 have shown in full lines, in Figs. 1 and 2, the normal position, In order to arrange the device's'o as to throw the outer end of the binder back when turning and forward whenstarting straight away the forward end of the cross bar is disconnected from the grain side of the extension bar and transferred to the opposite end, as indicated at 20. The lower end of the cross bar may remain in the extreme end of the movement translating bar or can be moved upwardlyin one of the holes farther toward the forward end of the cross bar, thus adjusting the swing of the machine. By re moving the cross bar and leaving the movement translating bar rigid with the plate the rigid bitch is provided, or, if desired the movement translating bar and cross bar may both be eliminated and the forward end of the grain bar itself bolted to the plate. the various bolts in both the forward mitting any desired degree of adjustment. In the event that the tractor has a long cross bar the extension bar can be dispensed with, although in ordinary conditions it is advisable to rovide the extension bar as shown in the drawings.

It will thus be seen that with my construction any degree of adjustment may be g obtalned by simply shifting the relative position ofthe grain bar cross bar and movem nt tra l ti g bar,-
